Space Hoppers - also known as Hoppity Hops, Hop Ball, and Kangaroo Balls - bounced into the UK during the Summer of �71 and served absolutely no useful purpose whatsoever.
They didn�t allow you to go faster, bounce higher, or run further than you could on foot. But you had to have one.
For much of the early 1970s children spent hours bouncing up and down busy roads until they either developed a headache, fell off and grazed their knees, or burst their Hopper - not an easy task unless it was cunningly over-inflated.
